Application led October 4, 1.913,.A Serial No. 7l-)3,307.

l State of Illinois, have invented certain new and useful Improvements in Hose-Couplings', of'which the following is a specifica'` tion.

My invention relates to improvements in hose couplings and has for its object the production of a coupling which will be durable yand economical in construction and through l the medium of which two eifds of hose 'may 'be readily 'and quickly coupled or through the medium of whic the end of a hose may be as readily and quickly connected with the tool in conjunction, with which the same A further object is the coupling which, when lin use, will be adapted to `maintain an absolutely tight connection against any pressure and which will be genscribed and claimed.

The invention will vbe which-- y l Figure 1f' is a central longitudinal section of acoupling embodying my invention, Fig.

2 is a cross section takenonline Elg.

1, Fig. 3 is a perspective view of'pne .ofthe ,Y

gripping members ofthe coupling detached, and'Fig. 4c is a section similar Figrlillus; trating my coupling employed ingponnecting the ends of -two hosev sections.

' The preferred -form of construction .as

illustrated in the drawing comprises a nipple 1 the opposite ends of which are externally screw threaded, said member 1 being 1n reallty simply a section of pipe or tubing. In using the coupling to connect a hose with -a tool the right hand end of the nipple l is connected with the tool. Over the opposite end of said nipple is iitted the end of the hose 2 which it is desired to couple as clearly shown. Loosely arranged around said hose end over theC nipple 1 is a plurality of substantially rectangular segmental gripping members 3 the inner surfaces of which are corrugated or beaded as shown in order to e'ectually grpfthe outer surface of the hose production" of ai.:A

understood reference to they accompanying drawing' forming a part of this specification, endg-.ilu

about which -the same are arranged. The

Shovvn,'the arrangement being such that said l gripping members maybe moved into gripping relation with the hose or released there# from by simply moving said sleeve -longitudinlly. v p The -sleeve 6 is held in positlons of longitudinal. adjustment or in operative positions byineans of an internally operative sleeve 7 one end ofwhich is in threadedl connection with sleeve 6, the opposite-end of said-sleeve 7 being in threaded connection with a Iiange 8v which is threaded upon nipple-1 as shown.

seen that in coupling a hose end with a tool, itis only required to it one end of the nipple 1 into theend of the hose. This being done `the gripping members 3 are arranged about the hose end and theisleeve 6 slid into engagement therewith to hold said gripping A members in position. Said sleeve 6 is then threaded into the sleeve 7 tol force the mem' lbers 3 into secure engagement with the hose, the latter in tur'n being forced by the pres- -Offmembers 3 into thespaces between thethreads of nipple 1 as clearly shown in Figi;` l 1 'of the drawings. The flange 8 is "preferablyjprovided with an extension 9 and [the-outervsurfac'e of the outenend portion of the sleeve is left plain and smooth in order -Still's'on wrench for rotating the fiange 8 or said sleeve 6.

to permit "of the use of a wrench such as the With the arrangement disclosed it willbe A coupling ofthe construction set forth isl extremely simple and economical and may be manufactured at a low cost and will be found very eiective in use.

In Fig. 4 is shown a form of coupling whichds used in connecting the ends rof. two hose sections. In this dorm the ends of the hose which it is desired to connect are arranged over the respective ends of the nipple 1. Two sleeves l6 are employed which engage over the opposite .beveled end s of the gripping members 3', the latter being of a length equal substantially to twice the length of the members 3,each end of each of the members f3 being of the same construction as the members 3 as will be readily understood. The flange 8" in tlusr form 1s dispensed'y with, the sleeve 7 being made long enough to enga e with the inner ends of both sleeves 6 Whic are employed in this construction. Each serves as a Wrench receiving flange for the other.

While l have illustrated and described the preferred forms of construction for carrying my invention into eect, these are capable of variation and modification Without departing from the spirit of the invention. ll, therefore, do not Wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications asrcome Within the scope of the appended claims.

Having described my invention what ll claim vas new and desire to secure by Letters Patent is:

l l. The combination with a hose, of y"a nipple adapted to enter said hose; a plurality of beveled gripping members arranged about the hoseg a threaded Wrench receiving member; an internally threaded sleeve threaded on said Wrench receiving member; and an internally beveled sleeve madera lcoiperatiizig with the beveled portions oit the gripping members and havingy exteorA -receiving ange threaded onto the nipple;

an internally threaded sleeve threaded on said Wrench receiving member; and an in ternally beveled sleeve cooperating with the beveled portions of the gripping members and having exterior threads opposite the beveled portions cooperating withA themternal threads of said sleeve, substantially as described.
